Sigekatu Kuroda

Sigekatu Kuroda is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sigekatu Kuroda rather than just read about it. In short: Sigekatu Kuroda (黒田成勝, Kuroda Shigekatsu; 11 November 1905 – 3 November 1972) was a Japanese mathematician who worked in number theory and mathematical logic. In 1942 he became a professor at the newly founded Nagoya Imperial University, where he stayed for over twenty years.

Key takeaways

Sigekatu Kuroda belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sigekatu Kuroda to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sigekatu Kuroda from memory before moving on to harder problems.

Reference excerpt

Sigekatu Kuroda (黒田成勝, Kuroda Shigekatsu; 11 November 1905 – 3 November 1972) was a Japanese mathematician who worked in number theory and mathematical logic.

In 1942 he became a professor at the newly founded Nagoya Imperial University, where he stayed for over twenty years. He was responsible for much of the effort in setting up its Department of Mathematics. He was married to the renowned number theorist Teiji Takagi's daughter Yakeo. The couple had three sons, all of whom became mathematicians, including S.-Y. Kuroda, who was a professor of linguistics at the University of California, San Diego. He published a text on the foundations of algebraic number theory with Tomio Kubota in 1963.

Worked examples

Example 1 — a first encounter with Sigekatu Kuroda

Start with the simplest possible case. Write down what Sigekatu Kuroda claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sigekatu Kuroda before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sigekatu Kuroda ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sigekatu Kuroda

In research: Sigekatu Kuroda appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sigekatu Kuroda in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sigekatu Kuroda is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1905 births, 1972 deaths, 20th-century Japanese mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Sigekatu Kuroda outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
